Subbases | Pavingexpert
The subbase layer is often the main loadbearing layer of a pavement. It is designed to evenly spread the load of the paving, and any traffic thereon, to the subgrade below. A wellconstructed subbase will aid drainage and prevent settlement and channelisation the phenomenon common on cheap installations of block paving, where two 'ruts' develop in the paving....

Concrete recycling
Concrete recycling is the use of rubble from demolished concrete structures. Recycling is cheaper and more ecological than trucking rubble to a landfill. Crushed rubble can be used for road gravel, revetments, retaining walls, landscaping gravel, or raw material for new pieces can be used as bricks or slabs, or incorporated with new concrete into structures, a material called ......

Advantages of Gravel Driveways | Networx
Concrete delivered to my home runs about 130 per yard, plus truck time at 75 an hour. This cost varies by your specific locality. Concrete, when used for driveways, is normally 4" thick a bit thicker than the layer of crusher fines I used. Labor to install forms, rebar or reinforced wire grid and its installation cost, plus the labor to pour, screed, and float my drive would have put ......
Why How to Use Recycled Crushed Concrete
· When any concrete structure, road, sidewalk or parking lot is destroyed, that concrete is often deposited in a landfill. Concrete is not biodegradable and unfortunately, will not decompose. Rather, it sits there taking up space and causing environmental problems. At the same time, new concrete is being created to begin the process all over again. There is a solution to this wasteful, expensive ......

Concrete Slab Surface Defects: Causes, Prevention, Repair
Use a 100mm (4in.) layer of compactible, drainable fill (not sand). A "crusher run" material, usually graded from 38 mm to 50 mm (11/2 in. to 2 in.) down to rock dust, is suitable. Following compaction, the surface can be choked off with a finegrade material to separate the vapor barrier from the concrete. 5. Avoid overworking the concrete, especially with vibrating screeds, jitterbugs ......
